Preventing Petya – stopping the next ransomware attack

Check Point’s Incident Response Team has been responding to multiple global infections caused by a new variant of the Petya malware, which first appeared in 2016 and is currently moving laterally within customer networks. It appears to be using the ‘EternalBlue’ exploit which May’s WannaCry attack also exploited. It was first signaled by attacks on financial institutions in the Ukraine, but soon started spreading more widely, particularly across Europe, the Americas and Asia.
